Boomer like to wait until we've just fallen asleep and then find the loudest thing he can to play with. I don't think he cares what is, be it a plastic spoon on the tile floor, or a metal food tin that he stole from the trashcan, or even the splash sound that my glasses make when he knocks them into the toilet bowl, it's all fun to him. I can't count how many times I get up to *ahem* use the facilities during the night and had to stop short because i noticed something unexpected like my glasses, contact case, or comb sitting in the toilet water.
